    No you cannot use it directly for half bridge topology. You need isolation between the high side and low side fet. I think an IR2110 is a good driver to fit after the SG3525 it can source and sink up to 2 amps of current. This will allow you to use even high power mosfets like IRFP460 etc. However for 500 watts IRF740 mosfets are enough.
